Aug 1, 2025During 2025-08, the Genesis team delivered notable improvements in simulation reliability and realism, focusing on gravity handling and sensor modeling. The gravity setter path was hardened to prevent updates before solvers activate, refactored to use a kernel-based update mechanism, and fortified with input validation and expanded tests to guard against regressions. A unified Sensor subsystem was introduced via SensorManager to create and manage sensors, including an IMU with configurable bias, delays, and noise, enhancing realism and testability of sensor data. These changes reduce runtime instability, improve physics fidelity, and enable dependable performance testing across simulations.
